AI Engineer with ~3 years of experience, focused on building clean, reliable LLM pipelines and Document AI systems. Previously worked as a core AI Engineer; before that, working across the full stack. These days my interest leans toward system-level AI: how the pieces fit together, how to make them verifiable, and how to keep them maintainable.
